At low operating temperatures objects under observation
(background) normally cool down to roughly equal
temperatures which leads to lower temperature contrast, and
to image quality (precision) degradation. This is normal for
thermal imaging devices.

CORRECTIVE ACTION
Reinstall the batteries
observing polarity.
Clean the battery
compartment, focusing on
the contacts.
Install fresh batteries.
Charge the power supply
(if required).
Do the calibration
according to section 8
"OPERATION".
Adjust brightness/contrast
by rotating the controller.
Activate the video output
(see point "Selection/
Disable of video output
